Performance of the Week: South Lyon East's Mason Crosby
October 30, 2026
Mason Crosby ♦ South Lyon East
Senior ♦ Tennis
Crosby completed a perfect season last weekend 30-0, with his final four wins at the Lower Peninsula Division 2 Finals earning him the championship at No. 1 singles. Top-seeded in the bracket, he clinched with a 6-1, 6-2 victory over Birmingham Seaholm’s second-seeded Carter Griffith.
This was Crosby’s third appearance in a championship match at the Finals; he finished No. 2 singles runner-up as a freshman and No. 1 singles runner-up as a junior. Crosby’s only losses those seasons came in those title-deciding matches, and his sophomore-year Finals ended with a first-round defeat against Griffith. Crosby finished with a four-year singles record of 123-5 – with those wins ranking 13th on the MHSAA career list – and claimed 19 victories this fall by 6-0, 6-0 scores. He also plays basketball for South Lyon East, and he’s hoping to continue his tennis career at the collegiate level. His brother Cameron plays at Kalamazoo College.

Performance of the Week: Whitmore Lake's Kaylie Livingston
November 8, 2024
Kaylie Livingston ♦ Whitmore Lake
Sophomore ♦ Cross Country
After finishing runner-up as a freshman, Livingston took the championship step to win her first MHSAA Final in this sport, claiming the Lower Peninsula Division 4 title Saturday at Michigan International Speedway in 18 minutes, 6.5 seconds. Livingston built an 8.6-second lead during the first mile and won the race by nearly 14 seconds, and in the process also led Whitmore Lake to a repeat team championship.
Livingston won 13 races total this fall, finishing second once and sixth among a field that included two more eventual Finals champions in the Shepherd BLUEJAY Invitational Elite race. She also plays basketball for Whitmore Lake, making the all-Michigan Interscholastic Athletic Conference first team as a freshman, and she's just a few months removed from winning the 3,200 meters, finishing second in the 1,600 and running on the winning 3,200 relay at the spring's LPD4 Track & Field Finals.
